This PR introduces a new `TEST_CASE` macro called `TEST_CASE_PERSISTENT_FIXTURE`. `TEST_CASE_PERSISTENT_FIXTURE` offers the same functionality as `TEST_CASE_METHOD` except for one difference. The object on which the test method is invoked is only created once for all invocations of the test case. The object is created just after the `testCaseStarting` event is broadcast and the object is destroyed just before the `testCaseEnding` event is broadcast.
The main motivation for this new functionality is to allow `TEST_CASE`s to do expensive setup and teardown once per `TEST_CASE`, without having to resort to abusing event listeners or static function variables with manual initialization.
Implements #1602

Did this, because with 3.0.1, the files
- catch_xmlwriter.cpp
- catch_string_manip.hpp
- catch_test_case_info.hpp
were missing
This led to some obvious and some obscure compile errors when compiling
with g++ 13.2.0 (std c++17 or c++20)
One of these errors being "Elaborated-type-specifier for a scoped enum
must not use the ‘class’ keyword"
Since this is a rather bad experience and debugging it is
time-consuming, I suggest to simply boost the recommended version in the
snippet which is likely copied by new Catch2 users
The existing formatting created one-element lists separated by paragraphs, when it would make more sense to have the paragraphs that are providing more information about one of those list entries be part of the list entry itself.
I think this makes the documentation easier to read in both markdown and html form, and should also improve the structure for assistive technologies.
* Add missing include for VxWorks build.
std::min is defined in algorithm provides std::min. It appears to be transitively included for most platforms. For VxWorks however this explicit include is required.
* Add option CATCH_CONFIG_PREFIX_MESSAGES to selectively prefix message macros only.
In contrast to CATCH_CONFIG_PREFIX_ALL, this will only prefix the following macros:
I.e. INFO, UNSCOPED_INFO, WARN and CATCH_CAPTURE
This is mainly useful for codebases that use INFO or WARN for their own logging macros.
Introducing a new DISCOVERY_MODE mode option, which provides greater
control over when catch_discover_tests perforsm test discovery.
It has two supported modes:
* POST_BUILD: The default behavior, which adds a POST_BUILD command
to perform test discovery after the test has been built as was
always done so far.
* PRE_TEST: New mode, which delays test discovery until test execution.
The generated include file generates the appropriate CTest files at
runtime and regenerates the CTest files when the executable is
updated.
This mode can be used in build-environments that don't allow for
executing the linked binaries at build-time (like in a
cross-compilation environment).
DISCOVERY_MODE can be controlled in two ways:
1. Setting the DISCOVERY_MODE when calling catch_discover_tests.
2. Setting the global CMAKE_CATCH_DISCOVER_TESTS_DISCOVERY_MODE prior
to calling gtest_discover_tests.
Closes#2493
